+
+The `Number.MIN_VALUE` constant represents the smallest positive numeric value that can be represented in JavaScript, which is greater than `0` but very close to it.
+
+## Syntax
+
+```pseudo
+Number.MIN_VALUE
+```
+
+**Parameters:**
+
+None
+
+**Return value:**
+
+A number (`5e-324`) which is the smallest positive floating-point value representable in JavaScript.
+
+## Example 1: Comparing tiny numbers with `.MIN_VALUE`
+
+This example checks if a number is smaller than JavaScript's smallest positive value:
+
+```js
+const tiny = 1e-324;
+console.log(tiny < Number.MIN_VALUE);
+```
+
+The output of this code is:
+
+```shell
+true
+```
+
+This confirms that `1e-324` is smaller than `Number.MIN_VALUE`, meaning JavaScript treats it as effectively zero.
+
+## Example 2: Using `.MIN_VALUE` in scientific precision checks
+
+This example determines if a number is too small to be considered non-zero in physics simulations:
+
+```js
+function isEffectivelyZero(num) {
+  return Math.abs(num) < Number.MIN_VALUE;
+}
+
+console.log(isEffectivelyZero(1e-325));
+console.log(isEffectivelyZero(1e-320));
+```
+
+The output of this code is:
+
+```shell
+true
+false
+```
+
+The function detects when a value is smaller than what JavaScript can reliably represent as a non-zero number.
+
+## Codebyte Example: Handling rounding errors in financial apps with `.MIN_VALUE`
+
+This example uses `.MIN_VALUE` to ignore balances that are too tiny to count as real money:
+
+```js
+const balance = 0.0000000000000000000000001;
+
+if (balance < Number.MIN_VALUE) {
+  console.log('Balance is effectively zero');
+} else {
+  console.log('Balance is non-zero');
+}
+```
+
+## Frequently asked questions
+
+### 1. Is `Number.MIN_VALUE` negative?
+
+No. It is the smallest positive number JavaScript can represent. It is greater than 0.
+
+### 2. What's the difference between `Number.MIN_VALUE` and `Number.MIN_SAFE_INTEGER`?
+
+`MIN_VALUE` is the smallest positive float value (`5e-324`), while `MIN_SAFE_INTEGER` is the most negative integer that can be accurately represented.
+
+### 3. Why does dividing `Number.MIN_VALUE` sometimes return 0?
+
+When a value becomes smaller than what JavaScript can represent, it underflows to 0.
